Electric Pump Partition Reinforcing Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric pumps in thermal management systems face a challenge in balancing the thinness of the partition to ensure magnetic field transfer efficiency while maintaining structural strength, leading to potential liquid leakage issues.
Innovation Solution
The electric pump design incorporates a partition with reinforcing ribs on its outer peripheral surface, which improves structural strength without significantly affecting magnetic field efficiency by isolating the stator and rotor assemblies and using injection molding to integrate the shaft as an insert, ensuring the partition's strength without increasing the distance between the assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the partition is made thin to ensure magnetic field transfer efficiency, then the magnetic field transfer efficiency is improved, but the structural strength of the partition is weakened
Solution Approach 1:
The patent transitions from a two-dimensional thin partition design to a three-dimensional structure by adding reinforcing ribs that protrude from the partition surface. These ribs extend in the height direction and are distributed along the outer peripheral surface, creating a multi-dimensional reinforcement system that strengthens the partition without increasing the distance between rotor and stator assemblies, thus maintaining magnetic field transfer efficiency while improving structural strength.
2Reliability
If the partition is made thin to avoid liquid leakage, then the structural integrity is improved, but the strength of the partition is weakened
Solution Approach 1:
The patent adds reinforcing ribs that protrude from the partition surface in the height direction, creating a three-dimensional reinforcement structure. These ribs are distributed along the outer peripheral surface of the partition and effectively increase the partition's strength and rigidity without significantly increasing the distance between the rotor and stator assemblies, thus maintaining liquid leakage prevention capability while improving structural strength.
3Strength
If reinforcing structures are added to the partition to improve strength, then the partition strength is improved, but the distance between rotor and stator assemblies increases
Solution Approach 1:
The reinforcing ribs are designed to protrude from the outer peripheral surface of the partition in the height direction, utilizing the vertical dimension for reinforcement rather than increasing the radial thickness of the partition. This allows the partition strength to be improved while maintaining a compact overall structure and minimizing the distance between the rotor and stator assemblies.
Solution Approach 2:
The reinforcing ribs are strategically distributed along the outer peripheral surface of the partition where structural strength is most needed, rather than uniformly thickening the entire partition. This localized reinforcement approach improves partition strength while minimizing the increase in distance between rotor and stator assemblies.
